To a/ZZ whoml t may con/cern.-

Be it known thatI, GEORGE A. OHL, Jr., a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and Au seful improvements in Metallic Lathing; and I do hereby declare the following to be afull,clear, and exact description ofn the invention, such as will enable others skilled in the art to which it appertains to make and use the same, ref# erencel being had to the accompanying drnw-v ings, and to letters of reference marked therel on, which form a part of this specification.

The present invention relates toimprovcments in sheet-metal lathing, such as is used in the construction of fireproof walls, ceilings, duc., which, owing to the cheapness of v construction and the many other advantages over the ordinary Wooden lath, is used to take the place of the latter.

The invention has for its primary object to provide a sheet-metal lath with pockets on one or both sides of the lath, said pockets being arranged and adapted to provide suitable openings for the passage of the filling or mortar into the same, and said pockets being formed with irregular or corrugated surfaces Which prevent thesliding of the filling within each pocket when in its green state, as Well as along the entire length of the lath, and as an extra precaution to prevent such sliding motion laterally the sheet may be provided with longitudinal beads.

A further object of this invention is to provide a sheet-metal lath which, owing to the corrugated or irregular shape of the pocket,

' becomes very sti and rigid.

Y A further object of the invention is'to provide, in connection with the sheet-metal lath having plaster or filling retaining pockets of the form above set forth ,some means for easily and quickly securing the lath in position by the use of nails or other suitable fastening means and without the use of an ordinary hand-punch for piercing holes inthe metal while securing the lath in place, as is now done by the Workman.

With these several objects in view my invention consists in the novel construction of sheet-metal la'th hereinafter set forth, as well as in the details of the construction and in sensi No. 675,067. N0 model the general arrangements and combinations of the parts thereof, all of which will be fully described in the accompanying specification and finally embodied in the clausesof the claim.

The invention is illustrated in the accompanying drawings, in Which Figure l is a plan view of a portion of a metallic lath embodying the principles of my i vention. Fig. 2 is a longitudinal vertical section taken on line w in Fig. l, and Fig. 3 is a vertical cross-section taken on line y in said Fig. l. Fig. 4 is a vertical section of a port-ion of a metallic lath in which there is a reversible arrangement ofl the pockets, but still made according to my invention; and Fig. 5 is a similar view of still another modified construction of sheet-metal lath embodying the principal features of my present invention. s

Similar letters of reference are employed in all of the above-described views to indicate corresponding parts.

In the said drawings, A indicates the body of the sheet-metal lath of the required dimensions, which is usually provided with longitudinal ribs or beads a. Said ribs serve a double purpose, in that they lstrengthen the metal sheet and also prevent a lateral sliding motion of the green filling .or plaster upon l the sheet While it is being applied, as will be evident. ever, absolutely necessary and may be dispensed with, if desired. As will be seen from said Fig. l, said ribs or beads form longitudinal panels, in which I have produced a row of shear cuts or slits a', the metal of the body A being forced upward at one side of each slit a and elongated, as at a2, to form the receiving-pockets a3, each being provided with an opening or aperture a4, substantially as illustrated. Said elongated portions are formed by means of( suitable roller-dies, each portion becoming suitably stretched Without breaking at the joints a7 and without in the least shortening the sheet A. Vhen Viewed from the top, the slit and aperture or opening ofeach pocket a3 practically forms a -shaped opening which permits of the plaster being more readily forced into said slit and the .opening of the Said ribs or beads a, are not, howtoo ' in Fig. 5.

` vor other suitable fasteningmeans.

' ing preferably arranged so that one row breaks joint with those of an adjacent ro'w, and also said apertures in two adjacent rows being preferably made to face each other, as clearly indicated in Figs. 1 and 3;- b utthisarrangef. ment is not 'absolutely necessary, forl the apertures or openings of the several pockets.

can be made to all face one way, as indicated The arrangement of said pockets as illustra-ted in Figs. 1 and 2 is the preferred construction, for thereby keys are 'formed for the filling material or plaster on the lines b b' and c c between any two pockets in adjacent rows, as will be clearly evident, and the filling will thus be very securely held in position on the metal sheet. Then, again, the sheet can be arranged in any position against the wail or ceiling irrespective of the arrangement of the pockets, while in the construction illustrated in said Fig. 3 each sheet has to be secured in place in such a manner that the openings or apertures of the pocket-s are upward to securely hold the filling or plaster in place upon the lath.

As will be more especially seen from Fig( 2, the surfaces of the portions azof each pocket may be made irregular or may be corrugated, which prevents the sliding of the filling or plaster longitudinally on the metal sheet, as well as within each pocket, and at the same time to considerably strengthen the lath coustruction by stiffening each portion a2 of the pockets; f

In Fig. 4 I have illustrated an arrangement of pockets which project alternately from the opposite sides of the sheet-metal plate, so that both sides have the same formation, and either side of the sheet can be used for .the securing of the filling or plaster thereon, as .will be clearly evident.

In sheet-metal laths as now made the latter are provided with, no means for fastening the same to the studding of the wall or to the ceil-v 'ing before the plaster or filling is applied and the workman must first punch a small hole in the sheet with a handpunch and hammer to enable him to tack the sheet fast with n ails This is a tedious procedure `and takes time, and to overcome this objection during the process of manufacture of my form of lath with the same shearing and presser rolls for forming the pockets I punch at suitable distances in the metal sheetv small holes a5, which are preferably made with the upwardly-projecting flanges a6, as illustrated in Figs. 1 and 3. It

willl thus be seen that all the workman has to do is to hold the sheet against the studding and nail it fast by means of nails, which are driven through the holes a5, or the sheet may be fastened by other suitable holding means, and the lath is then ready for receiving the plaster or filling.

`the same purpose as the ribs a in that prevent any sliding motion of the plaster or Said flanges a, which sur-V round the holes a5, as'will be evident, serve they filling when applying the same to the lath.

.From the above description it will be seen that I have devised a simple and cheap metallic lath provided 'with plaster or filling receiving pockets which more readily retain and .hold the filling on the sheet in its green state than in the constructions provided with projecting flanges as heretofore made, and also a double key on the lines b b' and c' c' is provided, which results in a more eiiicient construction of lath of the character and for the purposes stated.

" Having thus described my inventon,`what 1. A lathvconsisting of a metal plateliav#V ing a series of plaster or. filling retaining pockets, comprising an elongated aperture formed therein by a shear, and the metal ou one side thereof displaced by lbeing elongated outwardly and curved, substantially as set forth, and said elongated and outwardly-displaced metal portion having an irregular o1;

corrugated surface to .prevent sliding of the plaster within each pocket, substantially as and for the purpose set forth:

2.

3. A lathing consisting of a metal plate having a' series of plaster or filling retaining by a shear having curved or` IDO IIO

pockets, comprising an elongated aperture 4 forth, to form the plaster or filling retaining `pockets, the said pockets arranged in rows projecting alternately from opposite sides of the plate, and said elongated andoutwardlydisplaced metal portions having irregular or corrugated surfaces, to prevent the sliding of the plaster'within each pocket, substantially as and for the purpose set forth.

4. A lathing, consisting of a metal plate having a series of plaster or filling retaining packets, comprising an elongated aperture formed therein by a shear having curved or )shaped edges, and the metal on one side thereof displaced by being elongated outwardly and curved, substantially as setforth, to form the plaster or filling retaining pockets, the said pockets arranged in rows projecting alternately from opposite sides of the plate, and said elongated and outwardly-displaced metal portionshaving irregular or corrugated surfaces to prevent sliding of the plaster Within each pocket, substantially as `and for the purposes set forth.

5. A lathing consisting of a metal plate having a series of plaster or filling retaining pockets, comprising an elongated aperture formed therein by a shear, and the metal on one side thereof displaced byffpeing elongated ries of holes or perforations for nails or other fastening means for securing said plate 1n position, and a iange around each hole or perforation on the saine side of the metal plate with the said elongated and outwardlydisplaced metal portions; substantially as and for the purpose set forth.

In testimony that I claim the invention set forth above I have hereunto set my hand this 18th day of March,1898.
